    Question Complexes

    I am totally stack on where to start on this. I have these directions:
    Develop a class called complex. This class enables operations on so called complex numbers. These are of the form: realPart+imaginaryPart*i

    a. Overload the addition operator (+) to add two complex numbers
    b. Overload the subtraction operator (-) to subtract.
    c. Overload the multiplication operator (*) to multiply
    d. Overload the division operator (/) to divide
    e. Overload the == and != operators for comparisons
    f. Overload the operator (<<) to display the complex numbers.

    After hours and hours, this is what I got so far:
    #include <iostream.h>

    class Complex
    {
    public:
    ...

    Complex operator +(const Complex &op)
    {
    double real = _real + op._real, imag = _imag + op._imag;
    return(Complex(real, imag));
    }

    ...
    };

    Your help is appreciated, thanks.

    i would do this for you, but 2 things
    1) people on this board wouldnt like me very much
    2) i have alot of homework tonight but i can get you a head start

    Code:
    // some odds and ends
    class Complex 
    {
    	public://private:
    		double m_Real;
    		double m_Img;
    	public:
    		Complex(double Real = 1.0, double Img = 1.0);
    		Complex& operator=(const Complex& A);
    	//e. Overload the == and != operators for comparisons
    	//f. Overload the operator (<< ) to display the complex numbers.
    
    };
    // make these yourself
    Complex operator-(const Complex& A, const Complex& B);
    Complex operator/(const Complex& A, const Complex& B);
    Complex operator*(const Complex& A, const Complex& B);
    
    // constructor
    Complex::Complex(double Real, double Img)
    {
    	m_Real = Real;
    	m_Img = Img;
    }
    
    Complex operator+(const Complex& A, const Complex& B)
    {
    	return Complex(A.m_Real + B.m_Real, A.m_Img + B.m_Img);
    }
    
    Complex& Complex::operator=(const Complex& A)
    {
    	m_Real = A.m_Real;
    	m_Img = A.m_Img;
    
    	return *this; // A + B; also can be made another way
    }
    remember there is many ways to think of how to overload...many many ways!!!!!! this was my ugly fast thinking and i might be wrong...but i did this in 1 min...hehe
